You might want to get a larger fuel pump too. The stock one is fine for a 75 or 100 shot, but anything higher than that and you'll need to be flowing more fuel volume to compinsate for the system boosting your fuel pressure up to almost double what it is stock at idle. Either way it's wise to upgrade your fuel pump when using nitrous. But the Hobbs fuel pressure safety switch included in the dry kit will shut off the flow of nitrous into the motor if your not flowing enough volume and you are not able to maintain the jump in fuel pressure that the nitrous system requires. So it's "almost" fool proof...in a way.
Happy squeezing!
